Cancers that can spread from their original locations are called secondary cancers. This process,
called metastasizing, moves the cancers through the bloodstream, lymphatic system, or by direct
extension to a new location. One or many of the cancerous cells of the primary cancer (where the
disease originated) can break off and slip into the bloodstream or lymphatic system to reach other
organs.
Cancerous cells in the lungs as well can appear there without having originated there; in children,
cancers of the lungs usually manifest through this process. Cancer that appears in the lungs but
did not originate there is called secondary lung cancer. Even though it affects the lungs, this
cancer is named according to the type of cancer it originated from, the primary cancer. For
example, breast cancer that spreads to the lungs and becomes a secondary lung cancer would
still be considered breast cancer.
While nearly every type of cancer has the ability to metastasize and spread to the lungs, some do
so more commonly than others. Secondary lung cancer is usually a result of bladder, breast,
prostate, or colon cancer. Sarcoma, Wilms tumor and neuroblastoma also tend to migrate to the
lungs.
In addition to being a disease in itself, is also usually an indication that the primary cancer has
reached an advanced stage, though this is not always the case. Signs of lung cancer include
persistent cough, breathlessness, coughing up blood, and chest pain. These symptoms, in
addition to being similar to those for primary lung cancer, also mimic several less serious
diseases. A diagnosis of secondary lung cancer may therefore require x-rays, CT scans, MRIs,
PET scans, or biopsies.
Symptoms of cancers can interrupt daily activities for sufferers. But there are ways to manage and
treat the symptoms. Medication can help address symptoms such as breathlessness, cough and
chest pain. Other symptoms must be managed by the patient through awareness. Some patients
begin to fear they will choke, due to their increased difficulty with breathing, but should be aware
that this is unlikely. Others may be distressed by coughing up blood, but should know that
coughing up a little blood is not unusual to patients with cancer in the lungs. Only those coughing
up large amounts of blood need to seek treatment for this symptom.
Cancer of the lungs can also cause a build up of fluid in the lungs, a condition termed pleural
effusion. This fluid may be drained out of the lungs to relieve pain and difficulty breathing, though it
may build up again over time. Treatment for lung cancer is similar to that for primary lung cancer,
and includes surgery, chemotherapy, and radiation therapy. However, chemotherapy is the
preferred treatment option. This is because as a secondary cancer, it is an indication that the
primary cancer has spread into the bloodstream. In such cases, removing visible tumors through

surgery is not effective, as other cancerous cells can be present in the body without being visible.
Chemotherapy can target even those cells CT scans cannot see, making it the most common
treatment choice.
However, a cure is unlikely and the five-year survival rate for those diagnosed with secondary lung
cancer is not promising. The cancer can sometimes be cured via surgery, but this outcome is rare.

Adam Bradley is a book publisher of How-To and information books. While doing research on
asbestos and secondary lung cancer options, he was shocked by the tremendous amount of bad
information, scams, and bogus agencies. He felt that having to spend countless hours sorting
articles and web pages just to find help during a period when time is of the essence was absurd.
To help the victims and families of those exposed to asbestos, he and his research team compiled
this information and offer a free 15 part Mini-Course at: Asbestos Cancer Resources.com.
